Zusammenfassung:A method for coating a surface of a substrate may involve coating the surface of the substrate with a wet coating by way of a coating station, conveying the substrate by way of a conveying device, and detecting the surface coated with the wet coating by producing a thermal image of a detection region that comprises part of the surface. The thermal image may be recorded in a spectral range that includes a wavelength between 1 micrometer and 20 micrometers. Further, the detection region may be located directly downstream of the coating station, or the detection region may at least partially include the coating station.
